NEDA supports individuals and families affected by eating disorders, and serves as a catalyst for prevention, cures and access to quality care.

ANAD is the oldest organization aimed at fighting eating disorders in the United States. ANAD assists people struggling with eating disorders and also provides resources for families, schools and the eating disorder community.

There is a commonly held view that eating disorders are a lifestyle choice. Eating disorders are actually serious and often fatal illnesses that cause severe disturbances to a person’s eating behaviors. Obsessions with food, body weight, and shape may also signal an eating disorder. Common eating disorders include anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Signs and Symptoms

Anorexia nervosa

People with anorexia nervosa may see themselves as overweight, even when they are dangerously underweight. People with anorexia nervosa typically weigh themselves repeatedly, severely restrict the amount of food they eat, and eat very small quantities of only certain foods. Anorexia nervosa has the highest mortality rate of any mental disorder. While many young women and men with this disorder die from complications associated with starvation, others die of suicide. In women, suicide is much more common in those with anorexia than with most other mental disorders.

Symptoms include:

Extremely restricted eating

Extreme thinness (emaciation)

A relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight

Intense fear of gaining weight

Distorted body image, a self-esteem that is heavily influenced by perceptions of body weight and shape, or a denial of the seriousness of low body weight

Other symptoms may develop over time, including:

Thinning of the bones (osteopenia or osteoporosis)

Mild anemia and muscle wasting and weakness

Brittle hair and nails

Dry and yellowish skin

Growth of fine hair all over the body (lanugo)

Severe constipation

Low blood pressure, slowed breathing and pulse

Damage to the structure and function of the heart

Brain damage

Multiorgan failure

Drop in internal body temperature, causing a person to feel cold all the time

Lethargy, sluggishness, or feeling tired all the time

Infertility

Bulimia nervosa

People with bulimia nervosa have recurrent and frequent episodes of eating unusually large amounts of food and feeling a lack of control over these episodes. This binge-eating is followed by behavior that compensates for the overeating such as forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. Unlike anorexia nervosa, people with bulimia nervosa usually maintain what is considered a healthy or relatively normal weight.

Symptoms include:

Chronically inflamed and sore throat

Swollen salivary glands in the neck and jaw area

Worn tooth enamel and increasingly sensitive and decaying teeth as a result of exposure to stomach acid

Acid reflux disorder and other gastrointestinal problems

Intestinal distress and irritation from laxative abuse

Severe dehydration from purging of fluids

Electrolyte imbalance (too low or too high levels of sodium, calcium, potassium and other minerals) which can lead to stroke or heart attack

Binge-eating disorder

People with binge-eating disorder lose control over his or her eating. Unlike bulimia nervosa, periods of binge-eating are not followed by purging, excessive exercise, or fasting. As a result, people with binge-eating disorder often are overweight or obese. Binge-eating disorder is the most common eating disorder in the U.S.

Symptoms include:

Eating unusually large amounts of food in a specific amount of time

Eating even when you're full or not hungry

Eating fast during binge episodes

Eating until you're uncomfortably full

Eating alone or in secret to avoid embarrassment

Feeling distressed, ashamed, or guilty about your eating

Frequently dieting, possibly without weight loss

Risk Factors

Eating disorders frequently appear during the teen years or young adulthood but may also develop during childhood or later in life. These disorders affect both genders, although rates among women are higher than among men. Like women who have eating disorders, men also have a distorted sense of body image. For example, men may have muscle dysmorphia, a type of disorder marked by an extreme concern with becoming more muscular.

Researchers are finding that eating disorders are caused by a complex interaction of genetic, biological, behavioral, psychological, and social factors. Researchers are using the latest technology and science to better understand eating disorders.

One approach involves the study of human genes. Eating disorders run in families. Researchers are working to identify DNA variations that are linked to the increased risk of developing eating disorders.

Brain imaging studies are also providing a better understanding of eating disorders. For example, researchers have found differences in patterns of brain activity in women with eating disorders in comparison with healthy women. This kind of research can help guide the development of new means of diagnosis and treatment of eating disorders.

Treatments and Therapies

Adequate nutrition, reducing excessive exercise, and stopping purging behaviors are the foundations of treatment. Treatment plans are tailored to individual needs and may include one or more of the following:

Individual, group, and/or family psychotherapy

Medical care and monitoring

Nutritional counseling

Medications

Psychotherapies

Psychotherapies such as a family-based therapy called the Maudsley approach, where parents of adolescents with anorexia nervosa assume responsibility for feeding their child, appear to be very effective in helping people gain weight and improve eating habits and moods.

To reduce or eliminate binge-eating and purging behaviors, people may undergo cognitive behavioral therapy (CBT), which is another type of psychotherapy that helps a person learn how to identify distorted or unhelpful thinking patterns and recognize and change inaccurate beliefs.

Medications

Evidence also suggests that medications such as antidepressants, antipsychotics, or mood stabilizers approved by the U.S. Food and Drug Administration (FDA) may also be helpful for treating eating disorders and other co-occurring illnesses such as anxiety or depression. Check the FDA’s website: (http://www.fda.gov/), for the latest information on warnings, patient medication guides, or newly approved medications.
